Texan politicians are attempting to become the anti-California, pushing the most fascist nonsense possible to attract middle class and petite bourgeois reactionary dipshits into moving in, building up housing in the DFW suburbs, and then promising them low or no property taxes. I look at this and see a kind of really stupid real estate investment ad

A related possibility is that they are reacting to demographic change and the slipping status of Texas as a GOP bastion.

In addition to gerrymandering, just attract the voters you want. American federalism in action.
